Sore legs after drinking beer may be caused by irritation of nerve endings, or it may be caused by circulatory disorders, gout is also prone to induce this symptom. 1. Stimulation of nerve endings: when drinking too much alcohol, the metabolism of alcohol in the body will form acetic acid, which in turn may cause stimulation of the nerve endings in the legs, resulting in the symptoms of soreness. 2. Circulatory disorders: In daily life, excessive alcohol consumption can cause circulatory disorders, which in turn manifest the symptoms of lower extremity pain. 3. Gout: beer contains a large number of guanosine acid components, which will be converted into purine, so when gout patients drink alcohol, it will be metabolized into uric acid in the body. If there is too much uric acid, it will lead to limb soreness. To sum up, there are many reasons for drinking beer after leg soreness, if the symptoms can not be relieved after appropriate rest, it is recommended to consult a doctor in a timely manner to clarify the cause of the standardized treatment.
